Megan Fox is once again banging on about her obsession with sex, claiming she would rather stay in bed with a lover than spend the day out.

The Transformers star was recently voted World’s Sexiest Woman by readers of FHM – and marks her new title with a near-naked photo-shoot in the latest issued of the men’s mag.

And in the accompanying interview, she admits her sexual appetite is insatiable.

She says, "I have the libido of a teenage boy. I'd rather have sex all the time than leave the house."
